Unless you have unlimited time or financial resources, you can't make a great game without having a dialog with your audience. Game developers' instincts are not infallible and they need to be able to get feedback and suggestions from their audience. Unfortunately, some of that feedback might be 'die in a fire.'

edit: And there's also the matter of games with live service components, where you're in a state of constantly tweaking the game based on feedback, potentially for years.
